Power-assisted steering system, function
description
The function power-assisted steering system refers to steering the
machine. The machine's steering is power-assisted with pressure
from the hydraulic oil pumps.
Steering consists of steering wheel, steering wheel shaft, steering
valve, hydraulic oil pumps, priority valve, steering cylinder, link arms
and wheel spindles.
The steering wheel affects (via steering wheel shaft) the steering
valve which in turn directs oil pressure from the hydraulic oil pumps
to the steering cylinder. Between the hydraulic oil pumps and the
steering valve there's a priority valve which gives priority to oil sup-
ply to the steering valve before other functions, for example, load
handling. The steering cylinder affects the wheel spindles. There are
link arms between the steering cylinder and wheel spindles.
